Lasergestuetzte Diagnostik und Pruefverfahren. Analytische Grundlagenuntersuchungen zur Laserimpulsfluorometrie im ultravioletten Spektralbereich

New laser pulse fluorometers have been developed for analytical determinatin of achromatic substances by time-resolved fluorometry: a fluorometer for the nanosecond region is based on a nitrogen laser pumped dye laser with frequency doubling in connection with real time, sampling and boxcar technique, and a fluorometer for the picosecond region, which is based on an argon pumped titanium-sapphire laser with frequency multiplying in connection with time-dependent single photon counters. Examples given for application of the laser pulse spectroscopy in chemistry and solid state physics and demonstrating the potentials of these analytical tools include i.a. new fluorescence probes for trace metal ions, CdS colloids as fluorescence probes for hydrogen bonds and solvent polarity as well as the determination of aromatic hydrocarbons in water.
